1. SZ-2000 concrete pipe making machine has different types of SZ800x2000, SZ1200x2000, SZ1650x2000 and SZ2000x2000. They produce concrete pipes for diameter of 300-2,000mm and length of 2,000mm. 2. Roller axis support pipe mould and press concrete inside the pipe mould. When pipe mould with roller axis rotates in high speed, the concrete becomes solid pipe by action of roller press and centrifugal force.
